I am working on parsing a file as follows. I see a duplicate line for "ver."=3 and 5 because there is only 1 second difference (Mon Jan 15 08:24:02 vs Mon Jan 15 08:24:03) software prints it twice.
Also, of you see line for "Ver."5 "Complete Time" has one second difference. I would like delete lines which has rest of the fields matching in the line except "Time" or "Complete Time" column has difference of 1 or 2 seconds.

I need to get the Current Sunday date from todays date.
I have tried this but it gives previous week Sunday, expected date is 11 Oct 2020 (today is 13 Oct 2020)
Here are Today Vs Expected Values
Formula that uses this Date -> Result
10 Oct -> 04 Oct
11 Oct -> 11 Oct
12 Oct -> 11 Oct
13 Oct -> 11 Oct
14 Oct -> 11 Oct
15 Oct -> 11 Oct
16 Oct -> 11 Oct
17 Oct -> 11 Oct
18 Oct -> 18 Oct
19 Oct -> 18 Oct
=TODAY() - (WEEKDAY(TODAY()) - 1) - 7
With dates in column A, in B1 enter:
=A1-(WEEKDAY(A1)-1)
I have tried this but it gives previous week Sunday, expected date is
11 Oct 2020 (today is 13 Oct 2020)
You don't need -7. Simply try:
=TODAY() - (WEEKDAY(TODAY()) - 1)
and as the other answer suggests, replace Today() with the desired dates.
I have a range with a start_date, end_date and I want to get the same day of each month for the whole range, so here starting on the 30th of January I should get the 30th of each month:
start_date = Date.new(2019, 1, 30)
end_date = Date.new(2019, 12, 30)
range = (start_date...end_date)
dates = range.step(30).map(&:to_date)
dates
#=> [Wed, 30 Jan 2019,
# Fri, 01 Mar 2019,
# Sun, 31 Mar 2019,
# Tue, 30 Apr 2019,

I was using something like this for weeks but with months when you get to February for example it of course fails, so I would have to adjust to 28th.
I know I could loop and look at the month and do adjustments based on the start_date but it feels like a bad idea.
I think you can use either active support:
require 'active_support/time'
start_date = Date.parse('2019-10-31')
12.times.map { |i| start_date + i.month }
=> [

or adjust: #next_month:
require 'date'
Date.parse('2019-10-31').next_month # => Sat, 30 Nov 2019
Event model which has start and end datetime attributes in the database. I want to seed some random events but the event time should be proper.
For example:
6.times { date_range << DateTime.now + (rand * 21) }
generates
[Thu, 03 Aug 2017 21:22:48 +0530,
Tue, 08 Aug 2017 17:36:29 +0530,
Sat, 29 Jul 2017 06:19:51 +0530,
Sat, 29 Jul 2017 13:36:21 +0530,
Thu, 27 Jul 2017 15:08:55 +0530,
Fri, 04 Aug 2017 13:53:03 +0530]
which is the correct behaviour.
But how to generate random datetime like this:
[Thu, 03 Aug 2017 21:00:00 +0530,
Tue, 08 Aug 2017 17:30:00 +0530,
Sat, 29 Jul 2017 06:00:00 +0530,
Sat, 29 Jul 2017 13:00:00 +0530,
Thu, 27 Jul 2017 15:30:00 +0530,
Fri, 04 Aug 2017 13:00:00 +0530]
So in order to display these events properly on a calendar.
Could try separating out each segment and adding them onto the date individually
date_range = 6.times.collect do
DateTime.now.beginning_of_day + # starting from today
rand(21).days + # pick a random day, no further than 3 weeks out
rand(24).hours + # move forward to a random hour on that day
(rand(2) * 30).minutes # and then decide whether to add 30 minutes
end
or, could combine the hours + minutes
date_range = 6.times.collect do
DateTime.now.beginning_of_day + # starting from today
rand(21).days + # pick a random day, no further than 3 weeks out
(rand(48) * 30).minutes # pick a random interval of 30 minutes to add in
end
Found the working solution but not complete:
6.times { date_range << DateTime.parse((DateTime.now + (rand * 21)).beginning_of_hour.to_s) }

This can work for now but need some datetime with 30 minutes as well.
The user inputs the starting date and the end date. I want to get the dates between these two input dates.
I tried this:
(datestart..dateend).to_a
but it returns the whole month, and when I choose from the previous year, it gives an error ArgumentError (invalid date):.
This is the example return when I choose Jan. 1 2017 and Jan. 2 2017 - the result was whole month and an inaccurate dates.

Update! I Fix it by using
Date.strptime(params[:datestart_stat], '%m/%d/%Y')
start_date = Date.parse('date start')
end_date = Date.parse('date end')
(start..endd).to_a
Update! I was able to fix my mistake now. I just change the
Date.parse(params[:datestart_stat])
# to
Date.strptime(params[:datestart_stat], '%m/%d/%Y')
thank you guys.
We're in the timezone Bern, which is +0100. But since we're now in summertime (we have daylight saving time), the current offset is +0200. In my rails app, I set the timezone using a wrapper in the application controller since I need to have user-based timezones:
around_filter :user_timezone
def user_timezone(&block)
Time.use_zone(current_timezone, &block)
end
Now the strange part:
Time.zone.now # 2013-04-10 10:32:56 +0200
# (correct offset)
SomeArModel.first.created_at # 2013-03-28 17:49:59 +0100
# (incorrect offset, no DST)
Is there any explanation for this?
Thats normal behavior, the DST change happened on Sun Mar 31 01:00:00 UTC 2013.
t = Time.mktime(2013, 03, 31, 1, 15, 0)
6.times do
t += 900
u = Time.at(t.to_i).utc
puts t.to_s + " " + u.to_s
end
output:
Sun Mar 31 01:30:00 +0100 2013 Sun Mar 31 00:30:00 UTC 2013
Sun Mar 31 01:45:00 +0100 2013 Sun Mar 31 00:45:00 UTC 2013
